Hexar RF - Lens Mount

Lens Mount

The Konica Hexar RF accepts lenses designed for the "Bayonet Konica KM mount" a copy of the Leica M mount. Because of this, the Hexar RF can mount and focus lenses designed for the Leica and other compatible M mount cameras or, when used with an adapter, the earlier Leica thread mount lenses (note that due to physical constraints there is no adapter to allow bayonet mount lenses to be fitted to a Leica screw-mount camera).

When first released there was some controversy and discussion about whether the "Bayonet Konica KM mount" of the Hexar RF was, in fact, fully compatible with the Leica M mount . Some earlier testers reported problems using Leica lenses on Hexar RF cameras. Konica made no comment on the issue, and continued to refer to their lens mount by their own name, with no reference to Leica.

Other testers found no problems, and suggested that early reports may have related problems with early-production samples or to cameras at one end of a tolerance range matched with lenses at the other, and so claimed there was no systemic problem. The latter seems to have become the consensus view. Many users report using Leica and Konica lenses and cameras interchangeably with good results, including lenses of longer focal length or wider maximum aperture where problems are more likely to be encountered.
